Abstract

SE PROPONE UN APARATO PARA LA MEDIDA DE LA VELOCIDAD DE CORRIENTE O DE FORMA RESPECTIVA DE LA CIRCULACION VOLUMETRICA DE UN FLUIDO QUE DISCURRE EN UN TUBO (11) DE MEDIDA APLICADO EN UNA CONDUCCION TUBULAR Y QUE DISPONE DE UN CUERPO (20) DE REMANSO APLICADO EN SU CANAL (12) DE CORRIENTE, ESTANDO CONFIGURADO PARA LA GENERACION DE TORBELLINOS Y DISPONIENDO DE UN TALADRO (21) CIEGO UNIDO CON EL CANAL (12) DE CORRIENTE A TRAVES DE LOS PASOS (22,23,24,25,26,27). SE DISPONE ADEMAS DE UN SENSOR (30) DE TORBELLINO APLICADO EN EL TALADRO CIEGO CON UN CONVERTIDOR ELECTRODINAMICO CORRESPONDIENTE DE FLUCTUACION DE PRESION GENERADA EN EL TORBELLINO, DISPONIENDO DE UN ESPACIO (44) HUECO DESVIABLE DE LA FLUCTUACION DE PRESION, Y CERRADO CONTRA EL FLUIDO CON UN PRIMER CUERPO DE OSCILACION COMO VAINA (33) DEL SENSOR, QUE CORTA UN IMAN (46) PERMANENTE EN EL INTERIOR DEL ESPACIO (44) HUECO Y ABARCA UN SEGUNDO CUERPO (40) DE OSCILACION DESACOPLADO DE LA FLUCTUACION DE PRESION APLICADO DE FORMA MOVIBLE EN EL INTERIOR DEL ESPACIO (44) HUECO, ESTANDO EQUIPADO CON AL MENOS UNA BOBINA (47) ALOJADA DE FORMA OPUESTA AL IMAN (46) PERMANENTE.AN APPARATUS IS PROPOSED FOR THE MEASUREMENT OF THE CURRENT SPEED OR RESPECTIVELY OF THE VOLUMETRIC CIRCULATION OF A FLUID THAT GOES ON IN A MEASURING TUBE (11) APPLIED IN A TUBULAR CONDUCTION AND HAS A BODY (20) OF APPLIED REMOVAL IN ITS CURRENT CHANNEL (12), BEING CONFIGURED FOR THE GENERATION OF SWIRLS AND HAVING A BLIND DRILL (21) UNITED WITH THE CURRENT CHANNEL (12) THROUGH THE STEPS (22,23,24,25,26, 27). IN ADDITION IS A TORBELLINO SENSOR (30) APPLIED IN THE BLIND DRILL WITH A CORRESPONDING ELECTRODYNAMIC CONVERTER OF PRESSURE FLUCTUATION GENERATED IN THE TORBELLINO, PROVIDING A SPACE (44) DEVIABLE HOLLOW OF THE FLUCTU CLOUD AND WITH A FIRST OSCILLATION BODY AS A SENSOR SHEATH (33), THAT CUTS A PERMANENT MAGNET (46) INSIDE THE SPACE (44) HOLLOW AND COVERS A SECOND BODY (40) UNCOUPLED OF PRESSURE FLUCTUATION APPLIED FORMALLY MOVABLE INSIDE SPACE (44) HOLLOW, BEING EQUIPPED WITH AT LEAST ONE COIL (47) LODGED OPPOSITE TO THE MAGNET (46) PERMANENT.
